Psychometric properties of the Life Orientation Test (LOT-R) and its relationship with psychological well-being and academic progress in college students

Abstract

The aim of this study is to analyze the dimensionality of the Spanish version of the Revised Life Orientation Test (LOT-R), to examine the relationship between psychological well-being and dispositional optimism/pessimism in a sample of college students (n = 291), as well as to consider the effect of dispositional optimism/pessimism on academic progress. The results indicated that the properties of the Spanish version of the LOT-R (α = .72) were very similar to the original. The questionnaire clearly presented two partially independent factors, and the items assessing optimism demonstrated greater discriminant validity than the items assessing pessimism. Optimism was positively linked to psychological well-being and negatively related to psychological-distress. In the male students, a certain degree of preoccupation about academic results was linked to progress in studies, while excessive worry about academic progress could obstruct the successful completion of studies in the female students. These results suggest that the LOT-R can be used as a reliable and valid tool for the analysis of optimism and its positive effects on health and academic progress.
